@gamerdood123; how long have you had the car? If you bought it - say, in the last 2-3 weeks, then it might be worth taking back to the garage you bought it from, although there’s a good chance they won’t do anything, but no harm in trying - nothing ventured, nothing gained. However, if you’ve had the car a few months or longer, then the selling garage will probably maintain the damage that caused the corrosion has happened since your bought the car.
That sort of corrosion could easily have been prevented by the previous owner If the source of the corrosion had been spotted soon after it happened when the wheels were washed - spotting and repairing small chips and scratches on painted / powder coated alloys can be done easily using a paint touch up pen, provided the damage isn’t left unattended, when it could develop into a larger area of damage that requires a more extensive repair. It’s always worth checking the wheels and the car’s paintwork over each time you clean the car for new stone chip (or similar) damage and if there is any, repair it there and then.
The corrosion in the first three pictures on the wheel barrels was probably the result of careless removal of the stick on wheel balance weights by a tyre fitter when tyres have been replaced or repaired. That type of damage could go unnoticed if the wheel barrels aren’t washed when the car’s washed. The corrosion in the forth picture has probably spread from the small area of damage on the very edge of the wheel (either caused by a tyre fitter, or from wheel contact with a kerb) and the last two look to be the result of stone chip damage. Those last three - if spotted early on - could have been repaired and not developed into larger areas on corrosion.
Fortunately, your wheels aren’t diamond cut, so a DIY repair would be fairly straightforward if the Peugeot garage you bought the car from aren’t willing to get them repaired. Alternatively, you’d probably be looking at £60-£70 plus VAT per wheel for a good quality professional refurb.
